| 1. | 5 ) the allzyome variety of adiantum reniforme l . var 其次是与贯众,生态位重叠值为0 . 3389 。 |
| 2. | Simpson shannon - wiener methods for measuring niche breadth and wang - gang niche overlap formula are more fitted to ecotone Simpson 、 shannon - wiener生态位宽度公式和王刚生态位重叠公式对该区更为适用。 |
| 3. | It demonstrated that there is strong competition between two for nature resource . the value of the niche overlap with cyrtomiian fortunei is secondly bigger , it is 0 . 3389 4 )荷叶铁线蕨与鸢尾的生态位重叠最大,为0 . 3515 ,表明两者间存在强烈的对自然资源的竞争。 |
| 4. | The paper holds that the degree of competition between enterprises is proportional to their niche overlap in an enterprise ecosystem where the environmental resources are limited 在一个环境资源有限的企业生态系统中,企业之间的竞争程度与其生态位重叠的程度成比例关系。 |
| 5. | The two species with big niche in soil moisture , soil salt and organic matter overlapped greatly ( 0 . 4203 ) each other , indicating similarity of adaptation to soil salt 二者在土壤盐分维上的生态位重叠最大( 0 4203 ) ,表明了这两个优势种在适应土壤盐分方面有相以的特性。 |
| 6. | Whereas , for the natural forest consisted of native species , the niche overlap was low and the interspecies relationship was harmonious . the composition structure of community thereby was more stable 而由本地树种组成的天然林,生态位重叠小,种间关系协调,群落组成结构的稳定性更高。 |
| 7. | There are five natural sample zones of adiantum reniforme l . var . sinense y . x . lin investigated , and recorded 34 species . 10 dominant species were used to calculate the niche width of populations and the niche overlap interpopulations 调查了5个自然样地,记录了34个伴生种,取10个优势种进行种群生态位宽度与生态位重叠的计算。 |
| 8. | The result shows that the vast majority of the main tree populations in the ? castanopsis carlessii ? forest are of broad niche ; that the relation among the species is very complex ; and that many species share the same resources 采用定量分析方法,对武夷山米储林群落12个主要种群生态位(包括生态位宽度、生态位相似性比例、生态位重叠)进行了测定。 |
| 9. | In this study , the niche characteristics of 12 main tree populations in ? castanopsis carlessii ? forest have been analyzed by quantitative method at the nature reserve of wuyi mountains , including niche breadth , niche proportional similarity and niche overlap 植物种群之间的生态位相似性比例和生态位重叠指数指标值反映了亚热带常绿阔叶林的生态特征。 |
| 10. | In this paper , the niche characteristics of the dominant herb species in the subtropical ev - ergreen broad leaved woodland ( 53 species ) have been measured at the natural reserve of wanmu ling , including niche breadth , niche proportional similarity and niche overlap 对万木林自然保护区常绿阔叶林森林群落的53个主要种群进行生态位测定,包括生态位宽度、生态位相似比例、生态位重叠。 |
